Sunday starts with heavy outbreaks of rain in central and western areas, but eastern England is mostly dry. Through the day wet and windy weather pushes eastwards and there will be some very heavy bursts of rain mixed in. In exposed parts of the west and along the south coast winds may gust to gale force at times. This afternoon drier and brighter conditions return to Northern Ireland, Wales and western England, but much of the north and east have more rain.

Under the cloudy it will be a very cold day for the time of year with temperatures peaking at between 10C (50F) in the north and 14C (57F) in the south. The warmest conditions are likely to be in brighter parts of the west this afternoon where 19C (66F) could be reached. See the rain and lightning radar for the latest view

A mixed outlook for next week

Tuesday will be dry and bright in much of the country but cloud and rain spread into the north west later on. Temperatures continue to recover and in the south they approach 24C (75F).
